To'fLtZ-fi Lm'mnt it may concern.-

Be it .known that I, WILLIAM BARNUM (lowers, a citizen of the UnitedStates, residing at Cleveland, in the county of Cuyahogs and State ofOhio, have invented cer tain new and useful Improvements inBulkhead'JJoo-rs, Hatcl'ios, or other Barriers; and i do hereby declarethe following to be a full, clear," and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

Ally present ii'rvention relates to improvements in apparatus forelectrically operating 'lnilhheznt-doors or hatches or other barriers,and it is more es iecially intended to provide un oved moans tightbulkhead-doo'rs an hatches aboard ship, where the current-supply isrnoreorless limited, where the space available for the installatibn of theapparatus is exceedingly rkimtractcd, and where it is iecially desirable to avoid wastofulness in t re use of our- 'rent and to facilitatethe maintenance of the appatuatus in operative condition.

This invention more especially relates to moans tor controlling the o)eration of the motor at each door or hate either from a distance ingroups, or singly, locally at each door or hatch.

This invention relates to part of the apparat-us illustrated anddescribed in my appliration, Serial No. 21$;142, filed July 11,

1904, and entitled Electric system for operating bulkhcad-doors,hatches, &c., and it shows such ports as are herein described andclaimed in greater detail than they were shown in my earlier applicationaforesaid Thatapplication more especially described and claimed H114:mechanical means for operating the door, whether by hand orelectricnlly, the means ior operating the automatic ,cut-out, andvm-ious other details of con stru'ctim'i which are not claimed herein.

eniergency-stations-as, for instance, fromemergency-stations locatednear each end of the ship. In systems of thischaracter'it is essentialthat the apparatus shall be. operated either' electrically from'adistance or that it shall be operated electrically from a handfcontrollocated at or near each door or hatch, and also that it shall beoperated by mechanism wholly operated by hand. Tlns hand-operatingmechanism is not a part of-iny present invention, it being fullydescribed in my application, Serial No. 216,142, aforesaid.

As before stated, my present invention relates more especially to theapparatus whereby the door or doors may be operated by electroresponsivemeans from a distancer may be controlled by hand-control switcheslocated at or near thedoor.

In the operation on. board ship it has been i found in practice that itis desirable only to close the'door from a distance, but the mechanismmust permit of the local control of the door for either opening orclosing, and the apparatus must be such that the local control candominate the distant control. In other words, if the door is in the actof closing under i the distantcontrol, the system must permit of a manat the door opening that door in opposition to such distant control. InFig. 2 I have shown a form of controller which is operated by a solenoidthrough a circuit closed at the distant point H and which may be alsocontrolled by hand operated gearing locally, the hand control dominatingthe distant control. In this form of device "by means of the solenoid.

The partsare shown in the off position 110 and none of the circuitsclosed. Now if the the controller is normally brought back to the offposition by means of a suitable centralizing-spring. Iteferring morespecifically to the details of this figure, F represents thecontroller-drum, mounted upon the shaft F I and provided with a luralityof conductingsegments f to f T 1e controller-drum carries a lug or arm Fwhich is connected by the rod 9 to the solenoid-core G, the coils G ofwhich are connected to the central station H, Thus it will be seen thatthe controller may be rocked by this solenoid, causing itsconducting-segments. to enga c with the conducting-fingers k. to k, and51118 completing the circuit through the motor at the .door, as

will be hereinafter described.

'"The shaft F carries at its outer end the beyel-gear F, which mesheswith the bevelgear M", fast on the shaft M, passing through bulkhead andjournaled in bearings, (N 0t shown.) This shaft carries a set-collar M,having double cam-faces m, which engage corresponding cam-faces on thesliding collar M which is held a ainst turning on the shaft,

as by means of t e wings m which slide along any suitable guide-face'(not shown) on the controller-box or. bulkhead; Between this slidingcollar M and the set-collar M is a stout spring-M and at each end of theshaft M, one on each side of the bulkhead, are han- 9 5 dles M Byturning either handlein either direction the sliding collar M is weded-back against the spring M compressing t e same, and when the handleis let go the sliding collar M engagin the cam-faces m, will snap thehandles bac to the initial position. This is a form of centralizeremployed by-me but any other form of centralizer may be used, ifdesired.

It will be seen that by turning the handles lo 5 M the controller-drummay be rocked in either direction, while it may be rocked in onedirection only (the direction for closing) drum be rocked in thedirection of the arrow for closing, which may be done either by the handcontrol or by the solenoid, the contactfingers k to 1: will make contactwith the con- 1 1 5 tact-seginentsf to f, and the circuit will becompleted as follows: from the positive main to the finger kcontact-segment contactsegment 1, finger k armature-coils of the motorB, finger 7c, contact-segment finger 12o lc, field-coils of the motor B,contact-fmger k segment f, and finger 70 to the negative main.

The controller-drum may be moved by I hand, as stated, with the switchit at thc I emergency-station H open; but if this switch it be closed,the controller-drum being in the position shown in Fig. 2, theem'ergency-circuit will be completed from the positive main to theswitch h, to the solenoid-coils G, and 1 0 throw a owners to theneg'etive mein. This will energize the solenoii'l, which will rock thecon- .Ytroller tothe olosin position. i

- nive means from a distance are entirely independent-of each other; butif the power applied by the-hand mechanism is greater than that a pliedthrough the solenoid the hand contro may dominate the solenoid control.

It will be seen that the drum will be rocked b the solenoid to close thedoor, and it may arise be rocked by the lmnd-genr to close the doorindependently of the solenoid. Furthermore, it may be rocked b y thehand-gear to open the door, whether the solenoid is energized or not,provided the power ofqithe men at the door is sullieient to overpowerthe solenoid. Thus, Whether the solenoid is energised or not, if the manat the door rocks the controller-drum to the position for opening hewill cause the contact-segments f, f iindf to make contact withthefin'gers l" to Fe, respectively, and the current will then i'lm r inthe reverse direction from the positive Inein through the hing-(erit tothe segmentf, thence to the segmentf, thence through the nrmeture coilsof the motor to the finger k thence through the segmentf to the fingeris, thence through the series lield-coils of the mo or to the finger kthence through the SfiglhfiiliT-f to'tlle inger 7c and back to thenegative rnnin.

If the shaft of the controller projected g l. the liulkliend, this shaftmight be turn out tit.- lIllBI'POSlilOH of any gearing; but as it matterof convenience it is preferable to hevc the controllenboic secured tothe door with the cOntrollensheit parallel to the bulkhead, in whichcase gearing is required, and

since it is necessary to operate the controller i'roin either side ofthe bulkhead, a hand-control shaft passing through the bulkhead andfitted at each end with u hend wheel or hendle is required.

VVitl'i the form of controller shown in Fig. 9 it will be noted thatwhen said oonirollnr is operated from the distantor emergency stationthe solenoid must not only turn the wnitro ller through the requisiteangle, but it must also operate the lnrnd-gcoring and incidentally mustturn the bond wheels or the handles, and in so doing it must overpowerthe ceutrelizor. This would require it very strong solenoid under ovennormal conditions; but if either of the handles was obstructed'l'rointurning, us might happen from o li it ship or other obstrmrlious, then(he solenoid would not be able in turn the com trollcr all all, zmd(llll-llIlltIll-l)"llll distant opemlion would l'uil altogether. 'lonvoid thorn; conditions, it has been found in pron time more vouvcnieipto cause the solenoid by lin-ndcrunli or hand-wheel withto move aportion only of the controllerswitoh, but to have the parts so arrangedthat this movement of a. portion of said switch would accomplish thesome results as if the whole of said switch were turned.

To obviate the objections just stated with regard to the device shown inFig. 2, I have devised the form of controller-switch shown. in outlinein Fig. 3 and illustrated diagrammatically in Figs. 4 end 5, which, withslight alte'rzition's is. shown dingmmn'ieticelly in Figs. 6 end 7 andis shown in detail in Figs. 8 to 11. This controller-switch end themeans for operating the some will now be described.

Referring first to Fig. 3, the controllerdrum is made in two parts F andF, in which the port F is fast on the shaft F and F is loose on saidshaft, but is provided with atenon f projecting into n redial slot f inthe member F The member F of the drum is held in place by.thecentralizer, which, as shown, is precisely of the seme con struction asthat already described with referenoe to Fig. 2, while the member F isheld in the off position by means of thespring G which tends to pull thelug F down, causing the stopf to engage the end of the slot f Thisspring should be strong enough to re-. store the parts to the initial oroil position when the 6-11lUlgGTlGY-Clltllllt is open, but week enoughto be dominated by the solenoid core Ur when the emergency-circuit isclosed.

It will be seen that the member F is normolly in position for closingthe circuit for closing the door while the member F? is normolly in theoll position and that the mem ber 1 may be rocked, by means of thesolenoid, to the position for completing the circuit for closingregardless of the hand control; but at the some time it may be rocked bymeons'of the bend control against the action of the solenoid-spring" toclose the circuits or opening the door. Thus it will be seen that thewhole controller-switch is rotated. by the hnnd-genr, but a portion ofsaid switch only is rotated. by the solenoid, and it only booon'wsnecessary to arrange the oontnLit-fingers and Hie-segments on the controller in such imminncr that the turning of I n port of thecontrollur-switeh. may complete the circuit through the motor at thedoor. in other worils,'iristen.il of having the controllcr-switell closeall the contacts in the circuit at one operation it is sullicient tohave a number of these contacts normally closed, leaving: one or moreopen, endthen (r-losingthat one or more by the solenoid or content withcool or other ports ol the cargo other olootroresponsivc means.

In Fig. 3 l. have shown eight contoet-lingore L- to IE, while in Fig. 2only six of these contnrtdingers are shown; but this ndditiomd pair aremerely ndded u mutter ol n'leclmnicnl convoniirmw. The same circuitsmight be completed with six contoot-fingers the left-hand side of saidfigure shows the door in the operation of closing under the control ofth'eswitch h at the'emergency-station H, which has caused the solenoidco're G p to move the contacts f 7 and f 8 on the memher F, which areelectrically connected by flexible conductors f and f to the segments ofthe divided drum position to contact with the fingers k' and W. Thecircuit through the motor of the door will then he closed as follows 1from the ositive main toe segment f, V

the contact-finger It, to t thence through the flexibleconnection f tothe segmentf thence through the armature .of the motor B to the segmentf fithence through the field of the motor to'the segment f, thencethrough the flexible connection f to the segment fflthnce through thecontact-finger la to the negative main. The circuit through the solenoidfrom the emergency-station will be from the positive main 3 tothe-closed switch it at the emergency-station H and through thesolnoid-coilsG" and thence back to the negative main. The 0011-. trollerat the right-hand side of Fig. 4 is shown as in the opening positionunder hand control and overpowering the electroresponsive control. Thecircuit through the motor will in this case be as follows: from theposi-. tive main through the contact-finger k and segment f to thesegmentf, thence through the armature of the motor B f, thence throu hthe field-coils of the motor to the segment and thence to the negativemain. is thus completed through the motor the circuit through thesolenoid-coils will still remain closed or in the same position asindicated at-the left of Fig. 4. I-n'dther words, the current will flowfrom the positive main through the closed switch it at theemergency-station H, through the solenoid-coils, and down to thenegative main, as before.

Thus it will be-seen that when the controllerswitch is turned by hand tothe position for: opening thedoor the operator must manually overpowerthe effect of the solenoid, but without disturbing the circuit throughthe solenoid.

' eratin the'door or closing under 'the Fig. 5 shows thecontrollers attwo doors with the emergency-circuits both broken. The controller at theleft of said figure is indicated as in the osition for electricallylop-.

and contro In this case as the controller-drum is rotated in elongated'segmentsf f and f willremain .sition shown to the left flcu'it-s areclosedin precisely the same manner .as in the diagram to the left ofFig. 5 as in to the segment lt will be seen that while the circuit thedirection for closing the in connection with the contact-iimwrs 7c, k,k, and k until the limit of travel. 0? the con troller in --thisdirection is reached. At the same time the member F of thecontrollerdrum will be rocked by the stop f, engaging in the end of theslot j (see Fig. 3) until the contact-segments f and f engage thecontact-fingers 1c and k Thus it will be seen that the hand operation ofthe controller will accomplish the same result as the electroresponsivemeans in bringing these contactsegments f 7 an'dflinto contact with thefingers 7c? and W, as already described with ref erence to Fig. 4.-

Although the segment F of the drum has been rotated through an anglefrom the po'- in Fig. 4, still the cirthe diagram to the left of Fig. 4,and therefore it will be seen that the movement by the solenoid of aportion only of the controllerdrum accomplishes precisely the sameresults in closing. the circuits as the movement of the whole of thecontroller-drurn by hand. Thus it will be seen that when theelectromagnet operates the controller it moves only a portion of thecontroller without disturbing the hand-gearing at'all, which is a verygreat improvement over the device shown in Fig. 2, where it is necessaryfor the electromagnet to' move the hand-gearing and to overcome theresistance of the centralizer.

In the controller shown to the right of Fig. 5 the parts are in theposition for opening the door under the hand control, theemergencyswitchIt being open. In this case the circuits are precisely the same as thosein the diagram of the controller at the right of Fig.

4, except that in Fig.4 the emergencyswitch is closed, while in Fig. 5it is open. It will be evident from both of the diagrams referred tothat the emergency-circuit does nbt aiiect the action of the controllerin the operation of opening the doorr The diagrams shown in Figs. 4 and5 illustrate' a series-wountl motor but where it is des red to usea-compound-wound motor the arrangement of the controller-segments andcontact-fingers may be varied to suit altered conditions. With theinformation iven with reference to Figs. 3 to 5 such 'amodifiedarrangement would be a mere matterof 'mec'hanical'skiil. Such anarrangement is illustrated in Figs. 6 to 11.

Referring first to Figs. 6 and 7, these show, diagrammatically acompound-wound mo tor opera-ted in precisely the same way asthas alreadybeen described with reference to the diagrams shown in Figs. 4 and 5.The only material changes made in the controllershown in Figs. andfinger k for theshunt tor, the Widening of the contact-segment f 5 5 arethe addition of a "to engage said finger, the addition of theconfield-circuit of the moall'ect the operation of-the device.

This shifting ol: the contact-segments and fingers to the back of thedrum. is merely to enable a shorter drum to be used and does not,.in anyway Further more, the addition of the contaetd'inger 7c and adjustingthe segments to eorresp'ondis merely to throw in another circuit for theshunt li'eld coils.

The operation of the controller shown in Figs. 6 and. 7 is preciselysimilar to that already described with relcrence to Figs. 4

and 5.

Referring to Fig. 6, the left-hand controller is shown in' the oll'position, the circuit through the motor and itsshunt and held coils beng completefexcept that the segments f and f" are free from engagementwith the lingers la" and It, thus breaking the circuit to the mains.Furthermore, the emergcney s-witch It is open. in the con troller to theright of Fig. 6 the emergencyswitch It is also open; but the controlleris shown in position for closing the door under hand control. Thus theelongatedsegments f. andf have been moved down, but are istillinengagement with. the corresponding "contact-fingers, while the short sements j" and f 5 on the part F of the contrdller drum have also beenmoved down under the hand control, making contact with the fingers 7cand k Thus the circuit will be completed from the positive main andthefiriger k to the'segmentf through the llexible-connec-' tion 1' tothe segment Thence partof the current goes through the finger 1c" andthe shuntfield-coil to the finger k and thence through the flexibleconnection f to the tinger k" and back to the negative main. balance ofthe current from the segment-f passes through the finger 7c, thearmaturecoils of the motor B, and thefinger Ir, to the se ment 'lhenceit travels thro'u h. the

finger k to the series coil of the "motor and.

thence to the finger is, where it joins the shunteeurrent and returns tothe negative main with it.

In the two diagrams shown'in Fig. 7 theleft-band controller is shown inthe position it assumes when the door is closing hy emergency action,and the diagram to the right of 7 shows the emergency-circuit closed,

with the parts in the position assumed when thedoor is opening underhand control in. oppositlonto the einergmicy control.

it will be noted in this figure that both of.

the emergency-switches h and h are closed. and that thecurrent flowscontinuously through the solenoid-coils (if, tending to rock The themember F of the controller to the position for completing ther.;ircuitshf0r closing. in the left-hand diagram this is effected asfollows: The current flows l'roin the. positive main through the'finger1c, the contact-slag mentj', the flexible connection f to the sag.-rnent f'", where it divides, Part flowing through the armature of themotor and the rest flowing through-the shuntcoils, the cor'n-- binedcurrents so diiiided finally reaching the negative main through thefinger the segmentf, the flexible connection f and the finger it, asalready (lBSGlll'JBd.

In-the diagram shown to the right of Fig. 7 both members ofthecontroller-drum have been rocked by the hand control to the position foropening the door against the action of theicentralizer and also againstthe action of the solenoid,' and the solenoid-circuit still remainsclosed.

The current will flow as follows: frorri'the positive main to the fingerk on the back oi the drum, thence through the eontact-segf ment f alsoon the back of the drum, to the segment f, thence to the armature and.shunt coils of the motor, respectively, through the'seginents f and fand the fingers k and 7c", respectively. From the armature-coilsitpasses. through the finger k and segmentf to the finger 1c, thencethrough the series coils of the motor to the finger is, where it joinsthe current from the shunt-circuit and, entering the segment fhpasse'sto the segmentf", thence to the segment f and finger k both at the backof the drum, and thence back to the negative main.

ICC

' It will be seen-that the moment the hand control is released. thecentralizer ands-elem oid Wlll return the two members of the drum backtothe position shown in the diagram to J 11 the left 0!. Big. 7 andtherefore f this hand control he released during the act or opening thedoor, the emergency-circuit still be ng closed, the door Willautomatically close.

The controller illustrated diagrammatim 8 to 11.. In these figures Ishow not only controller-drum and its connections, but in the boxcontainin the controller I. show the limit-switch, which is intended toautomatically cut oil the current from the motor, as is described in myapplication Serial 'No.

' 216,142 aforesaid.

, It will be obvious that where a large nunber of doors are used aboardshipand there are no other automatic means for cutting off the currentfrom the doors when. they are closed by emergency that the current willcontinue running through all of themotors at all of the doors, not onlyunnecessarily heating up the motors, but more especially causing a greatwaste of current and throwing on unnecessary load'on the ships mains.

The supply of currelit aboard ship being; necessarily limited and therebeing a number ally in Figs. 6 and 7 is shown in detail in FIE? I whichwill prevent it from closin of'other appliances intended to be operatedby electricity in case .of emergency, this the ships mains is kep downto a minimum.

" Of'course this automatiic cut-out has nothing to do with the operationof the motor'orof the controller or of the emergenc -station, and it canbe omitted but it she d referably be included for the reasons areadystated) This inclusion of'the limit-switch in the controller-box is amere matter ofconvenience, as the same might be placed anywhere else.The limit-switch is indicated by thedrum Q and the contacts Q, whichdrum I is Gked by the arm Q engaging the crank l nft' e rock-shaft R,whose operation is fully-disclosed in my ap lication Serial No.

The controller-drum is made in two sections F and F, and the part F isnotched,- as at f, (see Fig. 11,) to engage the stop f of the part F..The twd parts are electrically connected together by means of theflexible connections f and f (Shown 216,142 aforesaid and W1 1 not befurther remost clearly in Figs. 8 and 9:) The smaller part F of the,controlleedrum is connected tothe core of the. solenoid by the-.rod g,'and this part of the controller-drum is restored tojthe initialposition by means of the spring G The insulating-plate f is provided.be-

Inasmuch the h and-control shaft M needs to. be rocked only through asmall angle in place of the bevel-gears MI" and F",- shown in Figs. 2and 3, I provide bevel-segments, as shown at M and F in Fig. 10, therest of the gear-teeth being omitted.
